1/4 Mile times inside...opinions please

[MattZ281LE]

1st Time at the track with my Mustang.

Ran a best of [email protected] with a 1.90 60ft

Lots of 13.2-13.3 runs @ 103-104 all in the 1.9 60fts.

Mods are listed below. Car runs very consistant. But I am having trouble really nailing the launch.

This is my 2nd time to the track ever (last time was 99)
This was Hagerstown/ Mason Dixon

What is the altitude there anybody know?

I was happy, although I was really hoping for 12.xx . It seems pretty quick for a stock bottom end 120k 302.

Car has never been tuned and no chip. I am at 38psi fuel/12 deg timing
at the Drag radials at 14psi.No short belt, all accesories and 3/4 tank of gas.


Shifting around 6k. My better times where shifting above 5800-6000.

Opinions, I think the car has more in it but I will be adding a Kenne-Bell Blowzilla in the next couple of weeks, So this will probably be my only NA runs.

Great times...You are very close to my mods and my times! I dynoed 280rwhp & 315rwtq.My best 1/4 time was 13.42 @ 103 without my AFR's or my Cam.

Mason is 600' above sea level I believe. Add some more FP to it, I think you are not running enough. I run 42lbs.

 

[BlueOvalStangGT]

Nice times, Ibet if you ran with 1/4 tank of gas or less youd be in 12's

 

[rudeone707]

nice times man. your almost seeing 12s.

 

[mattkimsey]

600' above sea level is about .05, lower your 60' one tenth=0.15, get a tune/chip 0.2, 1/8 of tank .05.....you'll be all in the 12's

Matt...I've looked at your dyno graph very closely and its is VERY close to mine. I really think your car should have another 4mph in it. Good news is that I think its all in the tuning...mess with FP, timing, and work on your driving and it'll show up.

What was the temperature like there? Also...600' is not enough to make a difference, I know as my home track is exactly 600'.

We have almost the exact combo. I'm running a Pro M 80mm mass air vs. your 77mm and I'm running 1.7 rockers. I hope to get it on a dyno by the end of the year.

How does it idle? Are you having any issues with drivability? I'm not happy with my idle, it seems to load up a bit too much.

FWIW I think a tune or a JMS chip will get you into the 12's. However, some guys with combos/hp similar to ours are getting 12's without a tune/chip. I think with some more practice your 60's will go down and 12's will be there.

I didn't see what rear gears you were running?

Definitley add some more timing and play with the FP. AFRs like a little more timing. As high as 18*-19* is not uncommon.

Thanks for the input. The car pulls very very hard out of the hole. I pulled most other cars until the 1/8 th and my 60's where good compared to most others racing. I got to where I was consistant in the 1.9-1.95 60's and even guys on slicks where only getting 1.75's so maybe not to bad there. I wanted to launch a little higher but the stock clutch probably wouldnt like it. I bogged a little off the line but if I launched harder my 60ft went up and I lost ET. Seems like a very delicate game. I am definately going to get a line lock, for a decent burnout to evenly heat the DR's

I am running 3.73's with upper and lower LCA's and welded SFC's.

Up top the car seemed strong too, I would like to see a little more on the trap speed..106-107 maybe. The timing is an issue. As the morning went and the track and tires got better my motor got hotter. I Iced down the intake a few times but the motor was running around 220. I didn't want to detonate and was conservative on the timing. I think if I can get the temp down to around 200 I can advance it up a couple of degrees and add a little fuel and see what happens.

I am going to compare this to my 99 Z28. I ran a faster ET than it does with street tires but the trap speed on my LS1 is 106+ indicating more HP and top end. The Mustang is by far easier to launch. I would have taken my LS1 up to the 1/8th But the 1/4 the LS1 is ahead. It really takes some work to get the 5.0 really fast, but its fun working at it and I enjoy playing with the car.

This will be the only chance to run the car NA. I will be adding the 2200 Kenne-Bell blowzilla and upgrading the cooling system and driveshaft in the next couple of weeks. Then I can beat up on my Camaro

 

[Killercanary]

220*??? That's your problem right there. Run the car at 150-160 and I'd bet you'd see a minimum of 105+mph trap speed. Do yourself a favor, before you put the blower on, go back to the track and let the car cool until it gets to the 150* range on an autometer gauage, or around the first bracket before the N of normal. You WILL go faster, enough that I think it will warrent another trip to the track just to show yourself how well it actually does run. 220* is WAY too hot, hell even at 200 mine is a pig. With my new rad and such I NEVER go above 180* and the car LOVES it and runs MUCH better at the track and on the street.

 

[tmoss]

Definately try to get running temps in the 180-190* area. Flush the cooling system lately? Remove the radiator for a really good flush. I assume you run a 180* stat right?

 

[94DreamGT]

What was your 1/8th ET and MPH? You were saying it was pulling hard to that mark...maybe it was falling off on the big end?

 

[SorsCode]

What type of fuel pump you got??? I still got the stock on and running 104mph also with AFR165's and cobra Intake. Mine is do to stock pump i bet.... October theres a track rental a bunch of us are going to so i'm going to raise the full pressure and see if i can fix my issue.

 

[MattZ281LE]

Cooling has always been a big issue, I just removed the AC from the car including the condenser. I think the radiator may just be old and inefficent. But I am going to upgrade it in the next week or two anyway.

I have a 255lph intank


My 1/8 was [email protected]

I would like to get back up to Mason Dixon and run it with some adjustments and maybe a short belt and less fuel in the tank....maybe 12.xx then.

Have to see if I can get the time. After all it is only my second time in 5 years
